A system and method for forecasting a price of a property in a first housing sub-market based on data related to a second housing sub-market are described. A price index is derived for the second housing sub-market, and an error correcting function is calculated for the first housing sub-market. A price index for the first housing sub-market is derived from the second sub-market price index and the error correcting function. An estimate of the price of the price of the property in the first housing sub-market is then provided. The estimate of the price can be used as the basis for an economic decision.

17. The method of claim 9 wherein the economic decision comprises a valuation of the property.
18. The method of claim 9 wherein the economic decision comprises a decision concerning a loan secured by the property.
19. The method of claim 18 wherein the decision concerning a loan secured by the property comprises a decision whether to purchase the loan.
20. The method of claim 18 wherein the decision concerning a loan secured by the property comprises a decision whether to guard against credit risk on the loan.
21. The method of claim 18 wherein the decision concerning a loan secured by the property comprises a decision regarding a course of action when the loan is in default.
22. The method of claim 18 wherein the decision concerning a loan secured by the property comprises a decision regarding pricing the property for foreclosure sale.
23. The method of claim 1 further comprising the step of: selling the estimate of the price of the property to a third party.
24. The method of claim 1 wherein the second housing sub-market comprises a market for single family houses.
25. The method of claim 24 wherein the first housing sub-market comprises a market for a market for two, three, and four family houses.
26. The method of claim 24 wherein the first housing sub-market comprises a market for multifamily houses.
27. The method of claim 24 wherein the first housing sub-market comprises a market for investment properties.
28. The method of claim 24 wherein the first housing sub-market comprises a market for manufactured housing.
29. The method of claim 24 wherein the first housing sub-market comprises a market for houseboats.
30. The method of claim 24 wherein the first housing sub-market comprises a market for commercial properties.
31. The method of claim 24 wherein the first housing sub-market comprises a market for land.
32. The method of claim 1 wherein the first housing sub-market comprises a ZIP code level housing market and the second housing sub-market comprises a county level housing market.
33. A computer-implemented method for forecasting a price of a property in a first market utilizing historical transaction data related to a second market, said method comprising: electronically calculating a price index as a function of time for properties in the second market based on the historical transaction data; electronically calculating an error correction for the first market using transaction data extracted from a first database for the first market and using transaction data extracted from a second database for the second market; and electronically estimating a price of the property in the first market based on the calculated price index for properties in the second market and the calculated error correction for the first market, wherein the properties in the first market are of a different type than the properties in the second market.
34. A method according to claim 33 , wherein said estimating a price of the property in the first market comprises: calculating a price index as a function of time for properties in the first market based on the calculated price index of the second market and the calculated error correction function; and providing an estimate of a price of the property in the first market based on the calculated price index for the first market.
35. A system for forecasting a price of a property in a first sub-market utilizing historical transaction data related to a second sub-market comprising: a first database containing transaction data from a first sub-market; a second database containing transaction data from a second sub-market; and a computer programmed: for calculating a price index as a function of time for the second sub-market, for deriving an error correction function correlating data in the first and second sub-markets using transaction data extracted from the first database for the first sub-market and using transaction data extracted from the second database for the second sub-market, for deriving a price index as a function of time for the first sub-market, and for estimating real estate transaction prices for the property in the first sub-market based on the price index and the error correction function, wherein the properties in the first sub-market are of a different type than the properties in the second sub-market.
36. The system of claim 35 wherein the first and second databases comprise publicly available databases.
37. The system of claim 35 wherein the first and second databases comprise proprietary databases.

40. A computer-implemented method for forecasting a price of property in a first sub-market with sparse transaction data utilizing historical transaction data related to a second sub-market with plentiful transaction data, the method comprising: electronically calculating a price index as a function of time for properties in the second sub-market; electronically calculating an error correction function for the first sub-market using transaction data extracted from a first database for the first sub-market and using transaction data extracted from a second database for the second sub-market; electronically calculating a price index as a function of time for properties in the first sub-market based on the calculated price index of the second sub-market and the calculated error correction function; and electronically providing an estimate of a price of the property in the first sub-market based on the calculated price index for the first sub-market, wherein the properties in the first sub-market are of a different type than the properties in the second sub-market.
